| 摘 要： | 为进一步探讨气调贮藏对冬枣贮藏质量的影响,研究了冬枣果实在低温(-1～-2℃)条件下,8个不同体积分数的气体成分(15%O2+0%CO2、10%O2+0%CO2、5%O2+0%CO2、2%O2+0%CO2、2%O2+2%CO2、2%O2+4%CO2、2%O2+8%CO2、2%O2+10%CO2)和1个对照(21%O2+0%CO2)处理对冬枣果实呼吸、组织相对电导率、叶绿素含量及果皮色泽的影响。结果表明:适当的低O2可降低枣果的呼吸强度、减慢组织相对电导率的升高、延缓枣果叶绿素的降解、延迟果皮转红;而贮藏环境中的CO2则会促进果实呼吸、导致组织相对电导率升高、促进叶绿素的降解和果皮的转红。2%O2+0%CO2的气体条件对冬枣贮藏最为有利。

| Abstract: | In order to further explore the effects of controlled atmosphere(CA) on Dongzao jujube fruit quality during storage,the effects of 8 different treatments with gas compositions(15%O2+0%CO2,10%O2+0%CO2,5%O2+0%CO2,2%O2+0%CO2,2%O2+2%CO2,2%O2+4%CO2,2%O2+8%CO2,2%O2+10%CO2) and one CK(21%O2+0%CO2) on respiration intensity,relative electrical conductivity,contents of chlorophyll and fruit skin color of Dongzao jujube cultivar were studied under the condition of low temperature(-1 to-2 ℃).The results showed that appropriate low concentration of O2 could result in the reduction of Dongzao jujube’s respiratory intensity,slow down the increase of pulp’s relative electrical conductivity,delay the degradation of chlorophyll in fruit and retard fruit skin changing to red;but CO2 could accelerate fruit respiration,causing increase of pulp’s relative electrical conductivity,promoting degradation of chlorophyll and fruit skin changing to red.The results indicated that the CA condition of 2%O2+0%CO2 was the best for storage of Dongzao jujube fruit. |
